Objectives of this project are to develop research and schematic designs, if required, for mobile lightweight easily erectable aircraft shelters. Activities of phase I will be centered on; (1) program development, (2) identification and critique of now available units as possible mobile aircraft shelters; and (3) Development of schematics for the proposed mobile aircraft shelters. Program development will address and define specific parameters and criteria that the shelter must meet in order to fill the needs of the U.S. air force for mobile aircraft shelters. Work under this part will be done with direct participation of the prospective user(s) to address all needs and functions of the proposed units. Part 2 of this phase will review what is presently available on the market in light of the program developed under part 1. This work will involve both literature search/review and visits to/inspection of manufacturers of the existing units. Under part 3, schematic design will be developed from the data generated from parts 1 and 2. Part 3 will represent the final production of phase I.
